The module helps installing packages on Windows and Linux.
The module installs two batch files. The first one
pymy_update updates existing modules. The second one
pymy_install installes necessary modules to do machine learning.
To get help on both:

pymy_update3--helppymy_install3--help

For example, to install packages for a datascientist:

pipinstallpymyinstallpymy_install3

The module will download and install many modules (see All modules listed by pymyinstall).
It includes numpy, scikit-learn, jupyter, pandas and many others.
If it fails for any reason - lost connexion -, run again the function with the same
parameter. If it fails again, you can skip the modules by filling the parameter skip.
To update modules:

pymy_update3

If some modules fail, they can be skipped by using option --skip=<modulescommaseparated>.
Both scripts can be used to install a subset of modules:

The module also includes a function
win_python_setup
which creates a setup with Python and R which modules and packages for a datascientist.
This function gives extra informations about module difficult to install
such as theano which
will disappear in 2018.
